Minvest delivers metallurgical studies and process evaluation that underpin technically robust and economically defensible project decisions under JORC (2012) and NI 43-101 reporting frameworks. Our metallurgical work focuses on understanding how ore characteristics, processing routes and recovery assumptions translate into real operating performance, cost and project value.

We undertake metallurgical programmes with a clear focus on feasibility-level realism. This includes the design, interpretation and validation of testwork programmes, selection and optimisation of processing flowsheets, and evaluation of recovery, throughput and variability risks that materially influence reserve conversion and economic outcomes.

Our metallurgical services are fully integrated with geology, resource modelling, mine planning and economic analysis, allowing early identification of inconsistencies between ore characteristics, process assumptions and downstream mine plans. This integrated approach reduces the risk of over-optimistic recoveries, underestimated costs or misaligned production assumptions that commonly undermine feasibility studies.

Minvest's role extends beyond advisory. We prepare, review and take responsibility for metallurgical inputs to PFS and DFS studies, ensuring that metallurgical assumptions are transparent, defensible and aligned with JORC and NI 43-101 disclosure requirements. Where required, we provide critical peer review and decision-level interpretation of third-party metallurgical work.

All metallurgical work is led by professionals with direct operational exposure, enabling practical assessment of processing risk, ramp-up behaviour and long-term plant performance. The outcome is metallurgical input that supports reliable feasibility outcomes, bankability and execution readiness.
